Carbine has flipped the switch on its C.R.E.D.D exchange service, which allows players to buy and sell subscription time in-game.
A single C.R.E.D.D costs $19.99, and once purchased it can either be consumed for 30 days of subscription time or sold on the C.R.E.D.D exchange to other players for in-game gold. Basically, if you know how to make a lot of in game gold then you will never have to pay actual money for your game time ever again. Or, on the flip side, if you have lots of money and want to earn some quick gold then you can buy loads of these and sell them.
